Apurse contains S 7.55 in quarters and dimes. There are

12 more quarters than dimes. Find the number of

quarters and dimes.

25 quarters 13 dimes

Step-by-step explanation:

If you subtract the extra 12 quarters from the total, you have $4.55 that can be made up of groups of 1 quarter and 1 dime. Since those groups are worth $0.35, there are $4.55/$0.35 = 13 of them.

There are 13 dimes and 13+12 = 25 quarters in the purse.
